Anna Zaiachkivska — the former Miss Ukraine who ditched her billionaire hubby in Italy for the Big Apple — doesn’t seem too shaken up after she was found in New York City and her husband threatened to sue.

Spies told us stunning Zaiachkivska was seen hiding in plain sight twice on Wednesday at pricey Upper East Side eatery, Nello.

A spy claimed Zaiachkivska was “with a blond female friend” having “Dover sole and several Bellinis” during lunch — then returned for dinner, “with a man” and was “having what looked like an argument.”

Zaiachkivska married Gianluca Cervara in December, but then disappeared only for him to recently discover via Instagram that his missing model wife was in New York.
